I always do SITD to stabilize my quilt so that it is easier to work on...I really stitch next to the seam line not in the ditch. I find it makes the quilt much stronger and if you use a matching thread or a neutral beige/grey thin polyester thread it does not show up. Some quilts with small pieces...I just use stitching around the blocks straight line as quilting..really stabilizes and does not take away from the design of the quilt. I personally don't like too much quilting that sort of takes your eye off the geometric designs.
